Exophthalmos as the initial presentation of metastatic prostate cancer.

Primary metastatic prostate cancer to the orbit is exceedingly rare. Benign lesions, including meningioma, have demonstrated PSMA expression and can be visualized using PSMA-based PET tracers. We report the findings of F-PSMA-1007 PET/CT in a 76-year-old man with progressive confusion and long-standing blindness of the left eye.
